Flushing system for a clogged drain

ABSTRACT

A flushing system is used to clean and/or clear clogged sinks, waste pipes, and/or toilets. It consists of the following components: a control nozzle, a drain attachment, a toilet attachment, foot pedal liquid pump, and a water hose for connecting these components to function as a system. Since the flushing system utilizes the application of the liquid pressure principle, it is required to be connected to a pressurized liquid source when the user chooses not to use the foot pedal liquid pump. An example of a pressurized liquid source can be a water main. A water nozzle is used as an option to connect between the pressurized liquid source and the drain or toilet attachments to control the liquid flow. A pulsating jet of pressurized liquid can be delivered from the outlet of either the drain or toilet attachment to effectively clear clogged pipes by the opening and closing motion of the water nozzle. This flushing system is flexibly designed so that various configurations can be assembled depending on the application needed and can be used where a water main is not accessible. Each configuration provides ease of use and a more solution than all other patented and currently available solutions. When not in use, the whole flushing system can be conveniently stored inside the foot pedal pump, giving it a very aesthetic appealing look.  
     Although the present invention has been described with respect to certain embodiments, examples, and applications, it will be apparent to those skilled in the art that various modifications and changes may be made without departing from the invention.

BACKGROUND OF INVENTION—FIELD OF INVENTION

[0004] This invention relates to the unclogging and cleaning of clogged sinks, waste drains, toilet pipes and toilets.

BACKGROUND OF INVENTION

[0005] Clogged sinks, waste drains, waste pipes and toilets are caused by accumulation of foreign material trapped in its flow path way. Consequently, over time this causes back up in drains, pipes, and toilets. They can be cleared by the following methods: Chemical, mechanical, or hydraulic (liquid pressure). Chemical product such as sodium hypochlorite, sulphuric acid and mechanical devices consisting of plungers and drain snakes, along with inflatable bulbs that use liquid pressure are widely available in the marketplace. Chemical generally either takes an excessive amount of time to be effective and corrosive that is harmful to the environment and results in some damage to waste drainpipes while removing the clog. Mechanical devices like the drain snake can damage sinks and toilets, which requires the user to have some basic knowledge of plumbing to remove fixture that may incur harm from these types of devices. Inflatable bulbs offer little to no control of the liquid pressure and require insertion into the pipe below the waste drain itself hindering the user, thus requiring some knowledge of plumbing for the device to be effective. Plungers with a hollow shaft where pressurized liquid passes through the suction cup are not available in the market, perhaps due to its impracticality as some dwellings have no accessibility to a water main or that the faucet supplies to a weak liquid pressure source.

[0016] Flood, in U.S. Pat. No. 2,781,166, foot pump is used to supply air pressure. It is not designed to hold liquid nor does it have the capability to fill with water.

[0017] Rankovic, in U.S. Patent No, 6,035,455, Portable Power Plumbing Plunger, is a stand-alone device. It is complicated and difficult to operate and requires the user to have both hands to operate the device, one to hold the device to the drain hold to create a liquid tight seal while the other hand needs to pump the handle to apply force to create the needed liquid pressure. The manufacturing step for this device is more involved than the flushing system.

[0018] Lundman, in U.S. Pat. No. 3,714,951, Conduit Flusher, (1973) and Tesh, in U.S. Pat. No. 3,792,708, Fluid Flow Director, (1974) require the device be inserted into the pipe or an adaptor. It functions by expanding the bulb to prevent back flow before liquid is fully channeled to clear and clean the clog. It does not have control of liquid pressure and flow.

[0019] Tharp, in U.S. Pat. No. 2,036,614 (1936), Drain Pipe Cleaner is designed with a flexible hos and needs to connect to a faucet and offers very little griping area to press the head to the mouth of the drain The head is not detachable and offers no option to control the liquid pressure.

[0020] Brown, in U.S. Pat. No. 2,336,592 (1943), Drain Cleaner, is designed with a suction ring and can be operated without a liquid source. It has a side arm for liquid source as well as a handle to press to device against the mouth of the drain.

[0021] Li, in U.S. Pat. No. 4,320,539, Drain Clearing Device, discloses an elongated pipe with a manually operated plunger valve that activates a flow of pressurized water. A side arm, branching from and communicating with the pipe, is attached to a source of pressurized liquid by a male means of connection.

[0022] Torti, in U.S. Patent No, 4,768,237, Toilet Plunger, discloses a tubular handle elements attached to a mushroom-shaped cup having a check valve to prevent a backflow of water. The female receptors on the opposite ends of the handle allow the connection to a pressurized source of water.

[0023] Davenport, in U.S. Patent No, 5,020,166 Multipurpose Liquid Pressure Plunger is designed to a have a resilient cone-shape cup, a rigid handle and an adjustable valve.

[0024] In conclusion, insofar as of all researches done and prior arts, no unclog systems, solutions, or devices formerly developed provide the versatile and ease of use options to clear and clean clogged drain and are available in the market. All configurations of the present invention for a clogged drain allow the user to have easy usage of the system while providing an effective solution to their clogged problems. This invention is a complete solution for clogged sinks, waste drain, waste pipes, and toilets.

[0135] Operation

[0136] The flushing system for a clogged drain assembles and operates in the following manner:

[0137] (1) For clogged kitchen sinks, referring to FIG. 6B, the drain attachment 2102 connects to the outlet of the water nozzle 1024 while the inlet of the water nozzle 1024 is connected to a pressurized liquid source. For convenience, the water nozzle 1024 can be omitted as seen in FIG. 6A when the foot pedal liquid pump 1102 is used to supply the pressurized water. The pressurized liquid source can be from a water main 1012 or from a foot pedal liquid pump 1102. Using either of the above mentioned configurations, the user aligns and presses the outlet of the drain attachment center to the drain hole of the sink. As pressurized liquid flows through the drain attachment 2102, said outlet prevents back flow liquid and splash, channeling all pressurized liquid from said attachment through the drain hole. This force breaks the clog and flushes the remnant in the drain pipe that causes the clog.

[0138] (2) For a clogged washbowl where a stopper is linked and controlled by a handle and where said stopper needs to be removed when a drain snake (auger) is used, the flushing system can be used in the following manner to unclog the clogged washbowl without the removal of the stopper. Configurations as described in operation (1) can be used. First, the drain hole needs to be kept open with one hand controlling the handle, while the other hand presses the drain attachment 2102 to the drain hole. Since the drain attachment outlet 2135 is bigger than the drain hole of the washbowl, all liquid flow through the drain attachment will channel around the stopper and down the drain hole, which would clear the clog.

[0139] (3) For open clogged waste pipes, the same configuration as described in operation (1) is applicable. FIG. 7A shows the configuration without the water nozzle when it is connected to the foot pedal liquid pump 1102. FIG. 7B shows the configuration with the water nozzle 1024 when connecting to a water main via a spigot 1022. The user aligns and presses the outlet of the drain attachment center to the waste pipe. The outlet diameter of the drain attachment is bigger than various standard waste pipes. As the drain attachment outlet 2135 caps the waste pipe, the inner concentric hollow cylinders of the drain attachment fit snuggly to the various standard diameters of the waste pipes, typically 1¼″ and 1½″ in diameters. When the pressurized liquid flows through the drain attachment, said attachment channels all liquid from said outlet through the waste pipe, preventing any liquid back splash. The liquid flow breaks the clog and flushes the remnant through the pipes to the main waste pipe.

[0140] (4) For clogged toilets, the toilet attachment connects to the water nozzle outlet while the said inlet is connected to a pressurized liquid source as shown in FIG. 8B. For convenience, the water nozzle 1024 can be omitted as shown in FIG. 8A when the foot pedal liquid pump 1102 is used to supply the pressurized water. The pressurized liquid source can be from a water main 1012 or from a foot pedal liquid pump 1102. To clear clogged (back up) toilets, use the above mentioned assembly and align and press the outlet of the toilet attachment center to the flushing hole of the toilet. When the pressurized liquid is released through the control nozzle, the circular disk made of flexible material of the toilet attachment seals the mouth of the drain hole as it is pressed downward and prevents back flow liquid and splash, channeling all pressurized liquid from the outlet through the flushing hole. This force breaks the clog and flushes the remnant through the pipes to the main waste pipe.
